One of the problems with "church growth" methodology is that it often promotes a kind of topical (surfacey) preaching, which by definition, lacks theological depth and precision (see 2 Timothy 4:1-5). It is "evangelical lite" (see Heb. 5:12-14; 2 Tim. 4:3-4). Over time congregations that are regularly fed milk fail to truly grow up; which is no small problem (see Colossians 1:28-29). Without a solid understanding of the orthodox faith (i.e. doctrine and theology) the flock of God will not learn how to discern. Paul put it this way in Ephesians 4:11-16; And He gave some as apostles, and some as prophets, and some as evangelists, and some as pastors and teachers, for the equipping of the saints for the work of service, to the building up of the body of Christ; until we all attain to the unity of the faith, and of the knowledge of the Son of God, to a mature man, to the measure of the stature which belongs to the fullness of Christ. As a result, we are no longer to be children, tossed here and there by waves and carried about by every wind of doctrine, by the trickery of men, by craftiness in deceitful scheming; but speaking the truth in love, we are to grow up in all aspects into Him who is the head, even Christ, from whom the whole body, being fitted and held together by what every joint supplies, according to the proper working of each individual part, causes the growth of the body for the building up of itself in love.
Given enough time this unbiblical approach to preaching and ministry always come back to haunt the Christian church.
